TANK FOE MOTOR-VEHICLES.

Specification of Letters Patent. Patented Sept 24a, 11912..

Application filed August 14, 1911.

Serial No. 643,865.

To all whom it may concern:

Be it known that I, HOWARD E. COFFIN, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Tanks for Motor-Vehicles, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to tanks for holding oil more particularly designed for use on motor vehicles and adapted to hold both the fuel and lubricating oils.

One of the features of the invention is the construction and arrangement of means for filling the tank, and a further feature is a construction by which all danger of leakage and diffusion of one of the oils into the other is avoided.

The invention therefore consists in various features of construction as hereinafter set forth.

ln the drawings,Figure 1 is a part sectional elevation of the tank as secured in position upon the motor vehicle; Fig. 2 is an elevation partly in longitudinal section.

A is a tank which as shown is of an oval cross section and of a length to extend completely across the chassis frame upon which it is supported through the medium of a saddle B and securing straps C. This tank is designed for use in the storage of both the fuel and lubricating oils, and to this end is divided by a partition I) into two compartments E and F. The compartment E for the fuel oil is preferably the larger one, and the compartment F is of such relative capacity as may be desirable. The partition D is designed to completely separate the liquids in the two compartments, but there is always danger of a leak occurring,

which would be unobservable and would permit the diffusion of oil from one compartment into the other, thereby rendering To guard against such a defect I have made-the partition D hollow and have prov ded a drainage opening connecting with the hollow space, as 111- Thus, if any oil from either compartment should leak through the first To facilitate the filling of the compartments of the tank, I have provided filler tubes arranged at the opposite ends of the tank in a position for convenient access from the sides of the car. These as shown consist of elbow fittings H, which are riveted or otherwise secured to the end heads of the tank and extend upward to or slightly above the highest point in the tank. Each of these filler tubes H is provided with a quick opening closure, preferably consisting of a cap I seated on the tube and provided with an annular gasketJ for contact with the seat. I K is a hinged lever to which the cap I is flexibly attached by a pin L, and a spring M sleeved about said pin.and housed within said cap serves to yieldingly press the latter to its seat.

O is a locking device for the lever, preferably a hinged arm which engages the cammed end P of the lever and may be quickly thrown up into locking engagement therewith.

The construction described is particularly useful where, as'in the case of racing, it is desirable to refill the tank in the shortest possible time. Thus, I avoid the use of a threaded cap for the filler tube, and substitute the quick-operating closure described. Furthermore, the arrangement of the filler tubes at the ends of the tank Where they may be released from the side of the car facilitates the operation of refilling.

What I'claim as my invention is:

1. In a tank for motor vehicles, a hollow partition dividing the space therein into a plurality of compartments, and means for indicating any leakage from either compartment into said hollow partition.

2. In a tank, a hollow partition for dividing the same into two compartments, said tank having a drainage opening connecting with the space within said hollow partition In testimony whereof I aflix my signatnre for the purpose described. in presence of two witnesses.

3. In a tank a hollow partition for divid- I ing the tank into two compartments with a HOWARD E. COF FIN.
